This pin accepts/provides the clock signal for the Clock
Synchronous Interface 0 (CSI0). It represents a secondary
function for I/O port PIO5[0].
This output is the transmit data for the Clock Synchronous
Interface 1 (CSI1). It represents a secondary function for I/O
port PIO5[5].
This input is the receive data for the Clock Synchronous
Interface 1 (CSI1). It represents a secondary function for I/O
port PIO5[4].
This pin accepts/provides the clock signal for the Clock
Synchronous Interface 1 (CSI1). It represents a secondary
function for I/O port PIO5[3].
This input is the reference voltage for the analog-to-digital
converter. Connect it to V
These are analog signal input pins for analog-to-digital
converter channels 7 - 0.
This input is the serial data input for the debugging scan
circuit. It represents the secondary function for I/Oport
PIO8[7].
This output is the serial data output for the debugging scan
circuit. It represents the secondary function for I/O port
PIO8[6].
"L" level input to this pin resets the debugging scan circuit.
It represents the secondary function for I/O port PIO8[5].
This input selects the mode for the debugging scan circuit. It
represents the secondary function for I/O port PIO8[4].
This input is the serial clock input for the debugging scan
circuit. It represents the secondary function for I/O port
PIO8[3].
"High" level input to this pin enables the CPU's debugging
function. It represents the secondary function for I/O port
PIO8[2].
This input is a debugging request signal from an external
device. It represents the secondary function for I/O port
PIO8[1].
This output is an acknowledgment signal to a debugging
request signal from an external device. It represents the
secondary function for I/O port PIO8[0].
